DISINTEGRATING-MACHIINIE.

Specification of Letters Patent.-

Patented. Feb. 20, 1906.

Application filed May 3, 1905. Serial No. 258.701.

of New Jersey, have invented certain new and useful Improvements inDisintegrating- Machines, fully described and represented in thefollowing specification and the accompanying drawings, forming a part ofthe same.

The present invention relates to that class of disintegrating-machineswhich is designed, primarily, to reduce sugar cane, beets, and othervegetables for treatment by the diffusion process to extracttheir sugar.

In machines having a drum covered with cutter-teeth for reducingsugar-cane it has been found difiicult to support the cane close to therevolving teeth, as the teeth are constantly wearing away, as well asthe edge of the'feedirig-table, thus producing a space in which thecanes are insufliciently supported. This change in the relations of theteeth and the feeding-table increases the natural.tend ency of theteeth'to drag downward without disintegration the stubs and ends of'thecanes which advance-t0 the cutters when each cane is nearly consumed.Another difficulty in the practical use of such machines is the renewalor replacement of the teeth when they are accidentally injured bycontact with a stone, spike, or steel tool which may be acci dentallyfed into the machine with a cane.

The invention furnishes an adjustable means for supporting the materialclose to the path of the teeth, and this is effected by beveling theforward edge of the'feeding-table upon its under side and fitting aplate to such bevel to project at the front of the table supported. Theplate is adjustable, so that it can be set as close as possible to thepath of the moving teeth. It also provides means for grasping thematerial in such a manner close to the points of the teeth that shortportions ofthe material may not be dragged forward withoutdisintegration. This object 1s attained by the cooperation of theupwardly-projecting edge of the supporting-plate with a series of dogsmount ed upon a shaft above'the late and constructed with their sides inc ose proximity, so that their lower sides extend over the entire lengthof the-plate, and thus press upon the whole surface of the material asitis fed to the drum. Where an adjustable plate is edge of the tableadjacent to the drum, the forcing of the plate up.- wardl to compensatefor wear brings its surface a ove the surfaceof the table and forms adam, which compels the juice expressed from the material to'accumulateupon the table and one object of the-invention is to prevent the escapeof'the juice which may be discharged from the material during thedisintegrating process, -and this object is atfitted to the under tainedpartly by inclining the feeding-table downwardly toward the cuttingdrum, so that the juice may flow into the disintegrated material, andpartly by means of a packing inserted. between the adjustable plate and'the forward edge of the table to-prevent the.

juice flowing backwardly along such plate.

The invention also in cases where an apron' carrier is employed fordelivering the material to the feeding-table of the machine providesmeahs for partially closing the space between the carrier and the edgeofthe table and for clearing such space in case it becomes clogged. Toprevent the whole drum from being disabled, ll connect the teeth withthe cutter-bars in such manner that they may be broken from the bar ifobstructed by accident without injury to the bar; and this object iseffected by forming the bars of cast metal and the teeth'with shanksembedded inthe bars in the operation of casting, such shanks having astrength less than. that of the-bar, so as to be broken withoutfracturing the bar in case any hard objectis encountered by the teeth. I

These improvements 'll be understood by reference to the annexeddrawings, in Which- Figure '1 is a cross-section of the machine near themiddle ofits length. Fi .2 is a side elevation'of one of the dogs, andig. 3 a section of the same on line 3 3 in Fig. 2; Fig. 4 is aifrontelevation of the. machine. Figs. 5 and 6 show a portion ofthe shell ofthe drum in endview and side view, respectively, illustrating thearrangement of the cutter-bars in the undercut grooves. Fig. 7 is a sideview of one cutter-bar,'and Fig. 8 a section'of the same at the side ofone of the teeth. Fig. 9 is a plan of the machine with only a portion ofthe feed-shaft illustrated and none of the feeding star-wheels, and Fig.10 is an elevation of the table viewed from the rear' 'edge'. Figs. 9and 10 are supplied to illustrate the flanges d, which support thefeedingatable 9. Over the table a feed-shaft e is supported andprovidedwith star-wheels f, as is common. Adjacent to the flanges (1side plates d? are extended upward from the table to retain the canethereon in the path of the starwheels. Y

The drurn'is shown with numerous longitudinal dovetail grooves g, theundercutedges of which serve to hold inplace the bars h, which The barsare shown in Figs.

carry. the teeth t. 7 and8 as formed of cast-iron, with the teeth ifhaving shanks u embedded in the bars by casting the bars around suchshanks. Each of the bars is cast in a chill, which forms smooth dovetailedges upon the bar and secures a uniformity in the size of the bars,

which enables them to fit detachably and interchangeably in the uniformgrooves g upon the drum. Each bar is formed with a dowelhole 71 near oneend to receive a split pin or cotter Z. (Shown in Fig. 5.) The hole '11in each bar is provided at theouter end with'a recess or counterbore jto receive the head of the cotter, and each groove in the drum isprovided near one end with a hole Fr, through which the cotter isinserted and the ends of the same bent upon the inner side of the shellto hold the cotter in place. The teeth upon the cutter-bars are spaceduniformly apart, and the hole 11 is shown upon each at a uniformdistance from the end tooth of the bar,

. and the holes 7:: in the grooves g are arranged at graduated distancesfromthe ends of the drum, so as to project the teeth from difien entcircles upon the periphery of the drum. The spaces between the teeth areshown in Fig. 7 three or four times as wide as the teeth themselves,which enables each tooth to cut the material freely and withoutclogging, and the disposition of the bars in the grooves in groups offour, as shown in Fig. 6, enablesthe teeth upon the bars to successivelyoperate upon the entire surface of the cane as they successivelyintersect the entire edge "of the feeding-table.

As the teeth upon the bottoms of the star wheels move forwardly infeeding, their points tend to lift the cane upon the side nearest thedrum, and order to strip the cane from the teeth dogs m are shownmounted upon the hubs of the star-wheels intermediate to the teeth ofsaid wheels and'projected (through an opening in the cover 8) as closelyas possible to the cutting-teeth i. The dogs are thickened at theirforward ends shown in Fig. 1.

n, as shown in Fi 3, so as to contact with one another and formacontinuous presser over the cane between the teeth f of the feedwheelsand the teeth 25 of the drum. Where the dogs are mountedupon the hubs ofthe is provided to limit their upward movement,

and such stop may be formed by the upper edge of the aperture inthe'cover 8, through which the dogs are projected into the casing, or byastrip secured along such edge, as To preventthe short ends of the caneas they are fed forward from be-y ing dragged from the feed-table d, theforward edge of the table is provided with anupwardly-projecting latewhich is set at it in close contact with the teeth. The sharp edge ofthe plate cuts into the under side ofthe cane and prevents it from beingdragged forwardly. j The forward edge of the feeding-table d is beveledupon its under side, and the adjustable plate p is shown in Fig. 1 heldbetween such beveled surface and a seat a u onf'the bed a and its frontcorner projects above an angle and made a justa 1e, so as to hold thesurface of the table in opposition to the corners of the dogs. Thecorner of the plate is'acute where it projects above the table, as thebeveled edge of the table lies at an angle with thepath of the rotatingteeth,

Screws 0 serve to adjust the plate p as close as is practicable to the.points of the teeth and such adjustment can be renewed whenever the edgeof the plate or the points of the teeth are worn. The cane or othermaterial is thus supported close'to the path of the teeth, and thepressure of'the teeth is directed toward the edge of the plate andopcrates to cut the material rather than to drag itforward. As the tabled is held h'om vertical movement bythe flanges d, the plate and itspacking are held firml in place upon the seat a and are movable only asthey are adjusted by the screws 0. -The edge of the plate where itprojects above the front corner of the table unavoidably prevents thecane-juice from flowing freely from the table into the disintegratedmaterial, where it could be utilized, and operates to retain a certainamount of the juice uponthe table.

To prevent the loss of this juice by leakage between the plate ,1) andthe table, a packing 'yis applied to the upper surface of the'plate p.

The end of an apron carrier g is diagram matically shown in Fig. 1,arranged to deliver the cane or other material to the'rear edge of thetable 0?. Such edge is shown formed with an upwardly-curved portion d,

so that the slats of the carrier may move tanrier is more or less andsecured by a latchw its operative position. By releasing the drop thestop 5 that it may handle can be moved'rearwardly to from the edge ofthe table, thusthe space to clear it at any time become'clogged. Thelatch 11; serves to hold the stop normally in its operative osition.

' VVilah the machine thus organized thecane can be transferred from thecarrier to the talatch the fully opening 'ble without any clogging atthe junction of the two, and the cane is fed to the cutterteeth in suchmanner that it is wholly reduced and no portion of any material lengthcan be discharged from the feeding apparatus without disintegration. Thedisintegrated material is thrown downward inside the bed bars each by anarrow withall the juice expressed from the canereabsorbed in its fiberand is removed by a conveyer or other suitable means. The teeth, asshown in Fig. 8, are preferably secured in the shank M, which is soroportioned as to break or pullout of the ar without fracturing the bar,and the operation-of the machine is therefore not deranged The;drawings'show the dogs n journaled fu on the shaft 6; but any othersupport for that in practice they t e rear ends of the dogs wouldsuffice, as the essential feature of the construction is the thickeningof the free ends of the dogs, so form a continuous resser beyond theirthinner parts which orm the stripper for the feeding-teeth f.

What I claim, and desire to secure by Letters Patent, is-

1. In a disintegrating-machine, the combination, with the cutter-drumhaving teeth projected therefrom, of thefeeding-table d, the shaft eover said table with feed-wheels f thereon, and dogs we operating asstri pers for the teeth of the feed-wheels and t 'ckened at theirforward ends to form a continuous presser on the surface of the cane,and the drum having the cover 8 with opening into which the thickenededges of the dogs extend close to the path of the cutter-teeth.

2. In a disintegrating-machine, the combi nation, with the 'cutter-drumhaving teeth. projected therefrom, of a feeding-table, the

shaft e over said table'with feed-wheels f :Iened edges of the 'fordelivering the shaft. between the teeth of the feed-wheels,

ando crating as strippers dogs, eing rojected beyond the. ends of thefeedjng-teet and thickened to contact withone another to form acontinuous presser on drum having the surface ofthe cane, and the thecover s with opening into which the thick-. dogs extend close to thepath of the cutter-teeth.
